Quantum 9700 user manual Rear Panel, External Trigger, Sync Out, Interlock, Serial Port

The charge level indicator illuminates when the capacitor bank is fully charged. The current monitor is an oscilloscope compatible reference voltage to monitor the current pulse, 1A = 100mV.

External Trigger

Trig In (BNC) -- external signal input to trigger the generation of pulses. Optoisolated input, 3-15V (>3mA). Pressing the RUN button in the external trigger mode arms the system and waits for an external trigger input.

Sync Out

This is a BNC connector which provides a TTL sync output when the instrument is fired. This signal is generated by the internal clock and therefore the actual pulse output will be delayed relative to the Sync Out as specified by the channel delay parameter.

Interlock

A switch is provided to arm/disarm the system. This switch is used with the interlock input on the rear panel to control pulse generation of the system. A READY indicator is provided to indicate that the rear interlock is satisfied and the arm/disarm switch is in the armed position. No pulses will be generated unless the LED is on. When the system is disarmed, a relay disconnects the bank voltage from the output jacks.

Rear Panel

Interlock

This is a BNC connector which must be appropriately connected to allow the instrument to generate pulses. The input must be shorted to satisfy the interlock.

Serial Port

This is a 9-pin D-sub connector for the RS232 interface that comes standard with the 9700. It is pinned to be directly connected to a standard IBM-PC serial port -- use a straight-through cable (not a null modem cable) to connect to a PC.
